Аннотация:In this paper we study the application of numerical evolutionary method
(genetic algorithm) for the problems of instability velocity maximization and
finding the best material properties distribution in axially moving layered webs
(panels and plates) is presented. The thermomechanical model has been worked
out for description of axially movement and transverse elastic deformations and
vibrations of composite materials including instability phenomena and corresponding
eigenvalue problem formulation. The aim of our studies has been
to investigate an effective layers composition and perform sensitivity analysis
of global optimal solutions and their dependence on geometric and physicalmechanical
problem parameters. A key point of proposed evolutionary optimization
algorithm is that the efficiency of the procedure is dependent on the
used averaging techniques and obtained analytical expressions for effective modulas.
